Administration With Without Sureties

If your mother created a will in which she named her sister (your aunt) to act as her executor, and if your mother did not name any alternate executors, and if your aunt died before your mom - then basically you have a will without a surviving, named executor. So your uncle is going to ask the court to appoint him to act as the personal representative of the estate - the person who will take care of all the probate assets and make sure that they are distributed properly.
 
As has been said many time on this site, the administration process is designed and intended to be a very open process. So you absolutely have the right to see the will. You also have the right to assent to your uncle’s appointment, or fight his appointment.
 
I am not sure how old you are and whether you have any interest in acting as executor, but as an heir at law you certainly have standing to act in that capacity. I cannot stress enough how important it is to consult with an attorney that specializes in probate law – right now! If you want to serve, or do not want your uncle to serve, then you have a limited window in which to act. Even after your uncle is appointed, you will benefit from having an attorney to advise you on the Inventory, Accounts, distributions, and all the other procedural issues that will (inevitably) develop. Good luck.
